Abstract—This work is directed to the development of the management system of electromagnetic lifting installation. To develop such control system it is necessary to create automatic system of switching the poles. The experiment model of levitation system is developed for carrying out prior experiments. The Arduino UNO platform on the basis of the Atmega328 microcontroller is chosen. In the work the description of L293D driver is presented and the principle of driver operation which is a part of the circuit is considered. Index Terms—Electromagnetic lifting installation, microcontroller, Arduino Uno, L293D circuit driver, pulse width modulation. I. INTRODUCTION This article is written on the basis of results of the researches which are carried out within grant financing of the Ministry of Education and Science of the RK on the subpriority of "Technology of minerals", on the theme "Justification and Development of Energy Saving Technology of Rocky Mass Dredging by Means of Creation of Electromagnetic Lifting Installation", and also on the priority "Power and Mechanical Engineering" on the theme "Development of the System of Automatic Control and Complex Protection of Energy Saving Electromagnetic Lifting Installation". Now there are not enough generalized theoretical and experimental studies which could be used while calculation and projection of the electromagnetic lifting installation based on magnetic levitation. The substance of the offered technology is concluded in application for rise and motion of skip of electromagnetic field force (a magnetic levitation) for realizing ropeless rise [1]. II. STATEMENT OF THE PROBLEM Ensuring skip motion in the horizontal as well as vertical direction requires the ordered switching of poles of electromagnets in the directing devices.

It causes the necessity of automatic control system development. During the motion skip is under the influence of forces various in their origin and character. The specified forces can be subdivided into electrodynamic and mechanical. The results of the experimental and theoretical studies for a range motion speeds inherent in installations with a magnetic suspender showed that the force of aerodynamic resistance of the air environment is the dominating making resultant force of the skip motion resistance. Forces operating on the skip from the air environment at the most common problem setting are defined by the main vector of aerodynamic force and its main moment concerning the center of masses. The experiment model of levitation system is developed for carrying out prior experiments [2]. III. THE METHOD OF CALCULATION The developed experimental model consists of one directing device and the cart moving on it. The circuit of the experiment model corresponds to Fig. 1. Fig. 1. The circuit of the experiment model. The directing device consists of the directing conductor and electromagnets. The directing conductor electromagnets with alternation of the south and north poles are established on the whole length. In the directing conductor there are grooves for hinges. On the cart two electromagnets with alternation of poles and hinges are established. Power supply voltage on electromagnets is given in the way that when unlike poles of electromagnets on the conductor and the cart are attracted, the similar poles of electromagnets make a start. Thanks to it the cart is set in motion. The motion speed of the cart is regulated by the electromagnetic force of electromagnets depending on power voltage [3]. The ratio of mass of electromagnet and its drag force matters. The Development of Control Systems Electromagnetic Lifting Installation Altyn A. Aikeyeva, Bakhyt A. Zhautikov, Kanat M.
